I have been using a 1960's Mullard 5AR4 in my 9.0 PS which I like over the stock tube or the Create or Golden Lion.
Interested in Members' Experiences with Rectifier Tube Rolling in Modwright PS 9.0 and 9.9
I switched several years back from a 5AR4 to the Phillips 5R4GYS in the
PS 9.0 power supply feeding my Modwright-Sony 5400es. I prefer the
midrange of the 5R4GYS over all of the 5AR4's I've tried including the
metal base one. I find the 5AR4 tube to be a little lean in that
application. This past week I tried both the Mullard GZ32 5V4, and a
1949 RCA 5U4G black plate in the PS 9.0 power supply. In a direct
comparison, both were clearer and had better instrumental separation
than the Phillips 5R4GYS in my system. The 5R4GYS was slightly superior
in bass heft. On balance the Mullard GZ32 is what I've chosen to keep in
my PS 9.0, at least until I'm able to try the Tung Sol 5U4G top getter
black plate.

Hi all, Better late than never. I've run all the above in my Modwright Oppo PS9.9 and recently have been using the GEC U52. It is superb with great detail, great bass, layering, separation and a huge soundstage....it also adds some body and weight to the music that wasn't there with most others, similar to the Philips 5R4GY in that regard but more refined. I was disappointed as well as a bit surprised that the "Holy Grail" Western Electric 422A seemed a bit bright and harsh. Anybody else here find that? Could be that it had tested new so not run in as yet. I plan on running it for 100 hours starting this weekend and will see what transpires, but for now the U52 is going to be tough to top! Thanks |
Thank you to everyone’s contributions here. I just ordered a GEC U52 today for my Modwright 205/PS 9.0 V10 There’s an epic rectifier thread @ Head-Fi and when some comments here echoed those I saw on the other thread and articles, I pulled the trigger. https://www.head-fi.org/threads/dubstep-girls-massive-5ar4-5r4-5u4g-rectifier-review-comparison-rect... |
